To all whom it may concern: 4

Be it known that I, ALFRED J. Hrrrnn, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and ln1- 'mixing Wheel and .connected with an air chamber, and a pump driven by the said mixing wheel and having its intake head extending into a reservoir containing oil or other liquid, the said pump discharging into the mixing chamber opposite the air inlet.

A practical embodiment of the invention is represented in the accompanying draw'- ings forming a part of this specification, in which similar characters of reference indicate corresponding. parts in all `the views.

Figure l is a sectionalside elevation of the carbureter; Fig-2 is a plan view of the same with the head removed; Fig. 3 is an inverted plan view of the head; F ig. 4 is a sectional plan view of the carbureter on the line iT-1: 'of Fig. 1; and Fig. 5 is a sectional plan view of the head of the pump, the section being on the line 5-5 of Fig. l.

A reservoir A or containing oil or other i liquid is provided at one side with an inlet chamber A having an inlet A2 connected with a source of liquid supply, and the said inlet Az'is provided with a valve seat A controlled by a valve B actuatedby a oat C arranged Within the reservoir A, the iloat having a lloat lever' C engaging the stem B o'i the valve B, as shown in Fig. l. By the arrangement-described the float C rises and, falls with the liquid in the reservoir Ato close and open the valve B eorrespondingly for the purpose of maintaining the liquid at a desired level in the reservoir A. 0n

. top et' the reservoir A is arranged a mixing D `and the air chamber F are provided with a head G having an air inlet tube G leadin g to an annular chamber G? connected with the upper open end of thecair chamber l?. ln the air inlet tube G is arranged a valve `or damper H, under the control of the operator, for regulating the amount of air passing through the tube G into the air chamber l?. The head G is provided with 'an outlet G3 connected with the upper open end of the mixing chamber D, and the said head G is adapted to be fastened to the engine so that the outlet G3 connectsl with the cylinder to produce a suction action in the mixing chamber D.

lVithin the mixing chamber D is arranged a revoluble wheel l having blades I attached to a sleeve I2 secured to a shaft Iainounted to rotatein suitable ballbearings J and J, of which the ball bearing J- is supported in the upper open end of the mixing chamber D while the bearing J is e attached to the under side of the plate E.

The lower portion l* of the shaft la is hollow and extends into a reservoir and on the lower terminal of the hollow portion 'lt of the shaft l is carried an intake head K having means whereby to force a desired quantity of the :fluid upwardly within the hollow shaft when the latter is rotated. To this end the said intake headl' is provided with a central. chamber K communicating with the hollow ofthe shaft, and the wall of which central chamber is provided with an opening K2 leading into a chamber K3 surrounding the wall of'the central chamber'. rlhis chamber K3 is formed between the inner wall and the outer wall l@ and contains helical flange formed en the l 'inner wall and constituting a luicl lifting I5 leading Ainto an annular chamber l formcd'by enlarging the lower end et the sleeve l2, as will be readily understood by reference to Fig. l. The chamber I is pr0- vided in vits outer wall with perforations l? staggered relatively to the perorations l, so that the liquid in passing through the perorations l5 strikes a solid portion of the outer wall oi' the chamber ll to divide or break up the liquid, which is"y ice lic

the coperation of the mixing wheels, and

in the sprayed condition passes into the lower end ofthe mixing chamber D. The -air chamber F is connected at its lower end by openings F" with the mixing chamber D so that the openings h" are directly opposite the 'perforations l? vand I5, that is, the

ai-r and 'atomizedv liquid pass into the chamberD at the lower end thereof, namely, below the blades I of the revoluble wheelI. When the engineis running and a suction is produced in the mixing chamber D the wheel I is caused to rotate and in doing so a rotary motion is given to the head K whereby the liquidcontained in the reservoir A which is drawn up the hollow portion It of the shaft i3 in the manner above described, is sprayed at the upper end of the hollow portion and fiinallypasses in a finely divided state into .the-inner or lower end of the mixing chamber D to mix with the air passing through Athe openings F from the air chamber F into the said mixing chamber. The gas and air during their passage through the mixing chamber D are intimately and thoroughly mixedby contact with the revolving blades l of the revoluble wheel i, and the mixture finally passes through the outlet G3 into the engine to be used as motive agent therein.

ln the lower end of central chamber K of the head K is arranged a valve L controlled by a screw NA screwing in the bottom of the reservoir A to permit of adjusting the. 4valve L relatively to the opening K2 to admit more or lessliquid `to the chamber K from the chamber K3.

The air chamber F and the reservoir A are surrounded by a. hot water. jacket O f having an inlet O and an outlet O2, the

inlet being connected with a hot water or steam supply so that the heated circulating medium heats the liquid in the reservoir A and the air passing through the air chamber F so that a rapid evaporation of the liquid taires place and a hot` mixture is formed prior to reaching the engine. The reservoir A is provided in the bottom with a draw-off cock l?, and a plug Q, is arranged in the bottom of the jacket 0 for drawing ofi ythe water therefrom whenever it is desired to do so.

The carburetor shown and described is,

very simple and durable in construction, and is arranged to insure a thorough and intimate mixture ofthe air and gas.

Having thus described my inventionfI secure by Letchamber and having a hollow shaft extending into the said reservoir, the hollow shaft being provided with a spraying device discharging into the inner end of the said mixing. chamber, an intake head within the said reservoir and held on the end of the said hollow shaft to rotate with the latter, and

a manually-controlled means for` regulating the infiow of the liquid to said hollow shaft at the said intake head.

2. A carbureter, comprising a reservoir forv containing a liquid, a mixing chamber having an'air inlet at one end and adapted to be connected at the other end with an engine, a revoluble wheel in the said mixing chamber and having a hollow shaft extending into the said reservoir, the said hollowshaft being provided with perforations in the said mixing chamber, and being provided with an annularsleeve having perforations staggered relative to the perforations in the said shaft, and an intake head within the said reservoir and secured to the said hollow shaft, the said suction head having a central chamber opening into the' said hollow shaft, the wall of said central" chamber being 4perforated, and the said head having a receivin chamber and. provided with an inlet for t e entrance of the liquid Vinto the said receiving chamber.
